Hello.
I bought saab injectors, Bosch p/n 0 280 156 023 for my A4'02 AMB engine.
They are 382cc at 3 bars.
Firstly, I corrected KRKTE to 0.07384 (from ME7 tunung wizard) and KVB from 316 to 425.
And after starting I has very rich mixture..And additive correction goes to out of limit..
What wrong with me?
Which tables I nedd to correction in additional?
I'm sorry for my English..

Are you using 4bar fpr?
KRKTE is too low but does not explain rich conditions.
For 3 bar fpr KRKTE should be adjusted around ~0.087 and KVB == 382.

After one more flashing problem solved  I'm using stock fpr, as I khow, it's 4bar. I use 0.07 KRKTE and I have -2.3...+1.1 lamba-correction on idle. Is it OK? And additive is about 4%.. Is it necessary to correct TVUB table? |

Thanks. 4% additive means rich condition?

Hello again..
Since 2 days of driving, I have MIL ind
and vag-com shows:
17544 - Fuel Trim; Bank 1 (add): System too Lean … 001 - Upper Limit Exceeded
Something wrong in my fuel system?
I have no changes of boost, just change the injectors nad KRKTE and TVUB tables..
Maybe my injectors are not really 382cc and I need perfomance test to check actual flow?
Are 2002 AMB having 4 bar fpr?

proffesor has been telling you the whole time that your injector calibration is off. Positive fuel trims == lean condition |

What I should do now?
Can I use these injectors or they are broken and I need a new set?

Sounds like a tuning issue to me. Have you tweaked your calibration or are you completely relying on that "wizard"? |

Injectors are not calibrated correct and that causes this MIL and probably driving variations.
As phila_dot says your tuning file needs adjustments.

Hi,
Thanks for posting the file. Let's have a look to it later.
First some extra questions to be sure : You have NO other modifications made, right ? ? ? ?
NO other turbocharger, NO other downpipe, ect, etc, to get more power, right ? ? ? ?
Thanks,
PvL
